Topper Migration Under Repeated Motion

Scheduled — no results yetCS-TST-005

Product revision: CS-MATTRESS-2026-08-A

Internal engineering test — not an EN, ASTM, CPSC or medical certification.

What are we testing?

Can repeated adult movement cause the full-width topper to move enough to expose an underlying mattress join or create a meaningful perimeter gap?

Why this test matters

The topper's job is to keep the sleeper off the module joins — so migration under realistic movement is the direct engineering question.

Method basis

Co-sleeping.com internal protocol using a documented 90 kg distributed body load moved laterally through a fixed travel distance for 500 cycles, on a bed fully assembled according to normal instructions.

Planned procedure (draft protocol)

1Mark all four topper corners and reference points.
2Apply the documented 90 kg distributed load at the fixed starting position.
3Move the loaded form laterally through the predefined travel, at consistent speed.
4Record topper position at 0 / 100 / 250 / 500 cycles.

Loads / conditions

90 kg distributed, ±150 mm lateral travel (defined before test), 500 cycles

What will be recorded

Longitudinal and lateral displacement at each corner
Maximum exposed edge movement
Whether any underlying module join becomes exposed
Module separation underneath
Cover/seam condition

Result

Scheduled

This test has not been run yet under the current documentation protocol. No result is published until a dated, signed internal test record exists for the stated product revision.
